Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, and in particular to a longitudinal steel bar positioner for a beam. Background Art

[0002] The longitudinal reinforcement of the beam is the reinforcement arranged along the length of the beam, which bears the tension and part of the pressure generated by the beam under various stress conditions. In a bending member, when the beam is subjected to bending moment, tensile stress will be generated in the tensile zone of the beam. The longitudinal reinforcement can effectively resist the tensile force with its excellent tensile strength, preventing excessive cracks or even fractures in the tensile zone of the beam. Different specifications will be selected for different building structures and stress requirements. In conventional construction, short steel bars are generally used between multiple rows of longitudinal reinforcements.

[0003] Since the longitudinal steel bars may be stepped on or collided during the construction process, the longitudinal force-bearing bars of the beam may be displaced, resulting in inaccurate distances between multiple rows of steel bars, changing the stress state of the longitudinal bars in the beam and leaving safety hazards to the structure. In view of the above reasons, the present application proposes a longitudinal steel bar locator for the beam. Summary of the invention

The fixing hooks 5 arranged equidistantly can better control the distance between multiple rows of longitudinal bars in the beam, so that the steel bars are positioned at the correct position, thereby ensuring the safety of the structure. Figure 2 As shown, the fixing hook 5 includes a horizontal section and a curved hook section, the angle between the curved hook section and the horizontal plane is 45 degrees, the length of the horizontal section of the fixing hook 5 is 10 mm, the length of the curved hook section of the fixing hook 5 is 20 mm, and the distance between the two fixing hooks 5 is 55 mm. Figure 1-5As shown, a rectangular groove 6 and an annular groove 8 are provided on one side of the fixing hook 5, the rectangular groove 6 is matched with the rectangular column 3, an insertion rod 7 is fixedly provided in the rectangular groove 6, two insertion strips are fixedly provided on the outside of the insertion rod 7, a plug hole 13 is provided on one side of the rectangular column 3, two slots 14 are provided on the inner wall of the plug hole 13, the plug rod 7 is matched with the plug hole 13, the arrangement of the plug rod 7, the rectangular column 3, the plug hole 13 and the rectangular groove 6 can ensure the stability of the fixing hook 5 during adjustment and support, and can improve the overall strength of the fixing hook, and prevent the fixing hook 5 from bending and sagging after stretching adjustment, the slot 14 and the insertion strip are movably connected, a plurality of positioning holes 10 are provided on the inner wall of the annular groove 8, two mounting grooves 11 are provided on the outside of the connecting tube 4, and a positioning structure 12 is provided in the mounting groove 11;

[0050] Combination Figure 6 As shown, the positioning structure 12 includes a rectangular block 121 for installation, the inner wall of the annular groove 8 is provided with two sliding grooves 9, the positioning hole 10 and the sliding groove 9 are communicated, the rectangular block 121 and the sliding groove 9 are movably connected, a receiving hole 122 is provided on one side of the rectangular block 121, a positioning rod 127 for positioning is movably provided in the receiving hole 122, a spring 124 is fixedly provided in the receiving hole 122, a guide plate 125 is fixedly provided at one end of the positioning rod 127 close to the spring 124, the guide plate 125 is fixedly connected to one end of the spring 124, the guide plate 125 and the receiving hole 122 are movably connected, the inner wall of the receiving hole 122 is provided with two limiting grooves 123, two limiting blocks 126 are fixedly provided on the outside of the guide plate 125, the limiting blocks 126 and the limiting grooves 123 are movably connected, the positioning rod 127 and the positioning hole 10 are adapted, and the positioning structure 12 can adjust the extension length of the fixed hook, so that the positioner can use steel bars of different sizes, thereby improving the versatility of the equipment.

[0051] When used in this embodiment, first place a prefabricated pad at the bottom of the positioner, and then place the steel bar above the fixing hook 5 on one side of the device. The equidistantly arranged fixing hooks 5 can better control the distance between multiple rows of longitudinal bars in the beam, so that the steel bars are positioned in the correct position to ensure the safety of the structure. When it is necessary to place steel bars of different thicknesses, the positioning rods 127 on each fixing hook 5 are squeezed inward at the same time, and the positioning rods 127 then drive the guide plates 125, and the guide plates 125 squeeze the springs 124. When the positioning rods 127 are separated from the positioning holes 10 and retracted into the receiving holes 122, the fixing hooks 5 are pulled, and the rectangular blocks 121 slide in the sliding grooves 9. When the positioning rods 127 are separated from the positioning holes 10 and retracted into the receiving holes 122, the fixing hooks 5 are pulled, and the rectangular blocks 121 slide in the sliding grooves 9. When the rod 127 moves to the position of the next positioning hole 10, the spring 124 pushes the guide plate 125 outward, and the guide plate 125 then drives the positioning rod 127 to make it pop out from the positioning hole 10, thereby positioning the fixing hook 5. If the extended length of the fixing hook 5 cannot adapt to the specified steel bar, continue the above operation. When the extended length of the fixing hook 5 adapts to the placement of the steel bar of the specified size, the operation can be stopped. The arrangement of the insertion rod 7, rectangular column 3, insertion hole 13 and rectangular groove 6 can ensure the stability of the fixing hook 5 during adjustment and support, and can improve the overall strength of the fixing hook to prevent the fixing hook 5 from bending and sagging after stretching adjustment.

The magnetic block 153 can be attracted by the slider 155 through magnetic force, so that the protective cover 154 is tightly attached to the protective cover 151, so that it is in a closed state, which has the effect of waterproofing and dustproofing. The top and bottom of the protective cover 154 are fixed with sliders 155, and the slider 155 is made of iron. Before adjusting the fixing hook 5, pull the handle 156, the handle 156 drives the protective cover 154, and the protective cover 154 drives the slider 155 to separate from the magnetic block 153. When the positioning rod 127 is exposed, the operation can be performed. After the operation is completed, the protective cover 154 is pulled in the direction close to the magnetic block 153, and the magnetic block 153 can absorb the slider 155, so that the protective cover 151 is in a closed state, which has the purpose of waterproofing and dustproofing, and can effectively prevent the internal original parts from rusting and causing the adjustment jam.
